How to Know If Paint Is Bad: And Why Your Cat Might Be a Secret Art Critic

When it comes to painting, whether it’s your living room walls or a masterpiece on canvas, the quality of the paint you use can make or break the final result. But how do you know if the paint you have is bad? And why does your cat seem to judge your color choices so harshly? Let’s dive into the world of paint quality, with a few unexpected detours along the way.
1. The Smell Test: Trust Your Nose
One of the first indicators that your paint might be bad is its smell. Fresh paint typically has a distinct, chemical odor, but it shouldn’t be overwhelmingly foul. If your paint smells rancid, like rotten eggs or mildew, it’s likely gone bad. This is often due to bacterial growth in water-based paints, which can occur if the paint was stored improperly or past its expiration date.
Fun fact: Cats have a much stronger sense of smell than humans. If your feline friend avoids the room after you’ve painted, it might not just be the fumes—they could be silently critiquing your color palette.
2. Texture Troubles: Is It Lumpy or Separated?
Good paint should have a smooth, consistent texture. If you open a can of paint and find it has separated into layers or has lumps, it’s a clear sign that the paint has gone bad. Stirring might help temporarily, but if the consistency doesn’t improve, it’s time to toss it.
Pro tip: If your paint looks like a failed science experiment, don’t try to salvage it. Your walls deserve better.
3. Color Changes: When Red Turns to Pink
Paint can change color over time, especially if it’s been exposed to light or temperature fluctuations. If your once-vibrant red now looks more like a dull pink, the pigments may have degraded. This is particularly common in older paints or those stored in less-than-ideal conditions.
Side note: If your cat seems to prefer the faded color, maybe they’re onto something. Cats are known for their impeccable taste, after all.
4. Drying Drama: Does It Dry Properly?
Bad paint often has trouble drying. If your paint remains tacky or sticky long after it should have dried, it’s a sign that the chemical composition has broken down. This can lead to uneven finishes, peeling, or even mold growth over time.
Bonus thought: If your cat leaves paw prints in the sticky paint, they’re not just being mischievous—they’re probably trying to tell you something.
5. Expiration Dates: Yes, Paint Has Them Too
Like milk or bread, paint has a shelf life. Most paints last between 2 to 10 years, depending on the type and storage conditions. Check the label for an expiration date, and if it’s past its prime, it’s better to replace it than risk a subpar painting experience.
Fun fact: Cats don’t care about expiration dates. They’ll still knock that old paint can off the shelf just for fun.
6. Mold and Mildew: The Unwanted Guests
If you notice mold or mildew growing in your paint can, it’s definitely bad. This is more common in water-based paints stored in humid environments. Using moldy paint can spread spores onto your walls, leading to bigger problems down the line.
Cat connection: If your cat starts sneezing around the paint, it’s not just because they’re dramatic—mold spores could be the culprit.
7. Performance Issues: Does It Cover Well?
Good paint should provide even coverage with minimal effort. If you find yourself applying multiple coats and still seeing streaks or patches, the paint may have lost its effectiveness. This is often due to the breakdown of binders or pigments over time.
Cat-approved advice: If your cat walks across your freshly painted wall and leaves no trace, congratulations—your paint is probably still good. If not, well, maybe it’s time to rethink your storage strategy.
8. The Can Itself: Rust and Damage
Sometimes, the problem isn’t the paint but the container it’s stored in. Rusty or damaged cans can compromise the paint inside, allowing air and contaminants to seep in. Always inspect the can before using the paint.
Cat wisdom: If your cat can open the paint can with their paws, it’s definitely time to invest in a better storage solution.
9. The Sound Test: Shake It Up
Give the paint can a good shake. If you hear a sloshing sound but no movement inside, the paint may have solidified. On the other hand, if it sounds like a maraca, the paint has likely separated and gone bad.
Cat commentary: If your cat joins in by knocking over other cans, they’re either helping or auditioning for a percussion band.
10. Trust Your Gut: When in Doubt, Throw It Out
If something feels off about your paint—whether it’s the smell, texture, or performance—it’s better to err on the side of caution. Using bad paint can lead to disappointing results and even health hazards.
Final cat thought: If your cat refuses to sit in the room after you’ve painted, take the hint. They’re not just being picky—they’re probably right.
